At the same time, the stability of the lifting rod workpiece during welding is improved, so that the welding quality is improved. The structural setting is simple, easy to operate, and suitable for popularization and use.

[0022] Among them, it should be supplemented that the clamping mechanism and the lifting mechanism both include a rotating assembly, which is composed of an internal threaded sleeve 202 and a side ring block 201 sleeved on the internal threaded sleeve 202, and the top of the upper groove recess 101 and the bottom of the long recess 102 are both provided with a vertical rotation opening, the inner side surface of the vertical rotation opening is provided with a first inner ring groove 105, the front of the positioning block 1 is provided with a horizontal rotation opening, the inner side surface of the horizontal rotation opening is provided with a second inner ring groove 301, and the front of the positioning block 1 is provided with a limiting hole 302 near the horizontal rotation opening, and the rotating assembly is rotatably connected to the vertical rotation opening or the horizontal rotation opening.

[0023] Furthermore, the internal threaded sleeve 202 located at the bottom end of the long recess 102 is threadedly connected to the lower threaded shaft 2, and the top end of the lower threaded shaft 2 is fixedly connected to the bottom support block 4 located in the long recess 102, and the left and right sides of the bottom support block 4 slide against the inner side of the long recess 102, and the bottom end of the internal threaded sleeve 202 is fixedly connected to the lever block 203.

[0024] Furthermore, the internal threaded sleeve 202 located at the top of the upper groove recess 101 is threadedly connected with the upper threaded shaft 5, the bottom end of the upper threaded shaft 5 is located in the upper groove recess 101 and is fixedly connected with a top pressure block 501, the top surface of the top pressure block 501 is fixedly connected with a top limit plate 502, the top limit plate 502 passes through the top of the upper groove recess 101 and is slidably connected with the positioning block 1, and the top of the internal threaded sleeve 202 is fixedly connected with a lever block 203. It should be supplemented that a concave arc opening is provided at the lower end of the front side of the top pressure block 501, so that the user can weld the upper short side through the concave arc opening, which is convenient for operation and greatly improves the welding efficiency.

[0025] Furthermore, the internal threaded sleeve 202 located at the front side of the positioning block 1 is threadedly connected with a transverse threaded shaft 305, and one end of the transverse threaded shaft 305 close to the front side of the positioning block 1 is fixedly connected with a transverse pressure plate 3, and the back side of the transverse pressure plate 3 is fixedly connected with a limiting clamping plate 303, and the limiting clamping plate 303 passes through the limiting hole 302. The end of the internal threaded sleeve 202 located at the back side of the positioning block 1 is fixedly connected with a plurality of protrusions 306, and the side ring block 201 rotates in the second inner ring groove 301, and the back side of the transverse pressure plate 3 is fixedly connected with a pressing block 304, which can extend into the long recess 102 to press the lifting rod workpiece to be welded in the long recess 102.

[0026] It should be additionally explained that a connecting column is fixedly connected to the middle of the side wall of the positioning block 1 , and a flange 104 is fixedly connected to the connecting column for fixing the positioning block 1 .

[0027] Working principle: First of all, it needs to be supplemented that, refer to Figure 4As shown, the lifting rod workpiece to be welded includes a slot block and a long strip block, and the parts that need to be welded are two short sides and two long sides. When using this tooling, the tooling is fixed by means of screws in the prior art in combination with the flange 104, and the slot block is placed in the upper slot recess 101. By pulling the pull block 203, the internal threaded sleeve 202 at the top end of the upper slot recess 101 begins to rotate. Since the top pressure block 501 is limited by the top limit plate 502 and cannot rotate, the height of the top pressure block 501 can be adjusted, thereby pressing the slot block tightly in the upper slot recess 101. Similarly, the long strip block is placed in the long recess 102, and by pulling the pull block 203, the internal threaded sleeve 202 at the bottom end of the long recess 102 begins to rotate. Since the left and right sides of the bottom support block 4 slide in contact with the inner side of the long recess 102, the lower threaded shaft 2 cannot rotate, thereby driving the bottom support block 4 to rotate. The downward telescopic movement lifts the long strip block placed on the top surface of the bottom support block 4 so that the long strip block reaches the top surface of the slot block. Similarly, the protrusion 306 is rotated again. Since the cross pressure plate 3 is limited by the limiting clamp 303 and cannot rotate, the cross threaded shaft 305 moves back and forth, driving the cross pressure plate 3 to move back and forth, so that the pressure block 304 presses the front side of the long strip block and presses the top end of the long strip block against the slot block. It should be noted that in order to keep the long strip block from tilting when the pressure block 304 presses the long strip block, a pad commonly used in the prior art can be placed on the back side of the long strip block according to the thickness of the long strip block at the long recess 102. The long strip block located at the long recess 102 tilts inward when the long strip block is pressed by the pressure block 304, so that the top end of the long strip block is separated from the contact position of the slot block, that is, the position to be welded.

[0028] By fixing the long strip block in the long recess 102, fixing the slot block in the upper slot recess 101 and pressing the top of the long strip block onto the slot block, the user can weld the upper short side and the long sides on both sides on the front side of the positioning block 1, and because the lower end of the rear window 103 is located in the long recess 102, the user can weld the lower short side on the back side of the positioning block 1, thereby successfully completing the welding in one go, reducing the dimensional instability caused by stress release during the waiting process, and through the setting of the clamping mechanism, the present tooling can be applied to lifting rod workpieces of different sizes, which greatly improves the practicability of the present tooling, and at the same time, improves the stability of the lifting rod workpiece during welding, so that the welding quality is improved.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
